GEORGE'H. FAHBNBRCR'OF OMAHA, ivniannsifm.'Y

To'aZZ 'whom t may conc-ern I f Be it known that I, GEORGE H. FAHREN- BRUCH, a citizenV of the UnitedStates, resid-- ing at Omaha, lin the county of Douglas vand .State of, Nebraska, have invented -certain .new anduseful Improvements in Rule Attachments, of which the following is a speciication. yi w My invention relatesto a1 new'and useful improvement-in attachment Ifor rulesof the foldable,type, and hasforan object to provide-an `attachment that is soy constructed that jwliensecured to the rule, the rule/.may be used as a square, furthermore the attach- Y vas at 9 atanangleof 90 degrees for, ahslight ment is ffornied.. at.- its.' lower'fend with Ta slightly bent portionY that forms av clip to .be passed-1 over the outer fold `of, .a pocket :so .that the" rule will lnot slip outof the pocket when the wearer bends over. l 4,

" Another object of my invention is to forin the` .attachment out of a single 'blanke of g metal, -sof'thaty the samejmay bek made in quantities with but little.nianufacturingex-l portion 9 against-theiside of the-garmfof the pense, also one set ofdies only yis needed to stamp 4the attachments outingreat numbers'. v Also another'objectof the principal form ofiny inventionl is to so provide .the attachment that its outstanding arm that functions asthe one arm of the squarewillfbe exactly at right angles to the rule, and it will be impossible to fasten the'attachment to kthe rule in any other than its correct position! With these and other objects in view, my

invention consists in certain new and novelV constructions as will hereinafter be described and pointed out in they clalms. f

In the drawings;

Figure l is a view showing the rule fas-v tenedto the pocket;

Fig. 2 is a plan view of the'invention, one of the arms of the ruleomitted'for thesake ofclearness; Y z

Fig. 3 is a side elevation of a rule and my attachment fastened thereto; -V

Fig. 4 is an end elevation of the same;

Fig. 5 is a perspective of the invention; and Y Fig. 6 is also a perspective of a slightly modified form.

Referring now to the drawings, and especially to Fig. 5, it will be seen that the in'- vention comprises an attachment for a Yrule that is preferably struck from a small singlev blank of metal and is formed with what I term a main body-portion 1, which' portion may be marked with the graduations 2, and

vover. such afold. @1 1 f x @At thev upper end vof the body portion an arm 8 isprovid'ed ithat isfbent downwardly lwardly to formthe resilient retaining clip 1716 the endof this clip also being slightly Fig. shows the. ruleff,y Withuthe clip'f distance and is designedtdcontact with a formed at exactly 90 degrees tothe-body portion il, and by having/the{downwardly .sideface of lthe arm to whichithe body". porltin is ,nailed or screwed. ThisQa-rrn' 8 fisy bent rvportion 9 extending about-halffthe lengthof the-body portion when-,the attachmentf'is secured'fto the rule by fplacingthe rule beforenailing the same tothe-rule the This yarm- 8 1s `also `-`inches and parts thereof so that the rule may be used `as 'a square whenever-desired;A lz'eferringto Figs. lto 5 inclusively, it will 'also be vseen vthat byjhaving this offset porrtion 9, the arm of the rule that is adjacent to the arm to whichfthe bodyportion isV attached rests on the upper surface of the arm 9, when the rule is in a folded position. This is also an advantage, as the arms of the rule .may be openedorshut in the ordinary way without determining which arm should be opened or closed first.

yIn Fig. 6, is shown a modification ofthe attachment, the only difference in construcftion being that thearm l0- is not offset from the body portion 11 butwsimply extends at right angles to it.; Y It is providedwith the'` spring clip 12,'and with the graduations 13,r`

and the small holes 14 so that the same may be 'nailed or screwed to the rule. With this form. however, care has to be taken that-the attachment is correctly alined when being fastened to therule, as it has no offset guiding` portion as mentioned in the preferred form.

Also the adjacent arm ofthe rule itsunder the arm l1 so that the rule has to be opened tersPatent is:

from the side rather than as they fancy desires.

kFrom the fore-going it will be seen that the attachment is exceedingly simple, may be easily stamped out in great quantities with but `relatively little expense, and may be quickly secured'to a rule so that the attachment may be sold separately or may be nailed to the rule before it is sold.

With the preferred form 'it is impossible to get the attachment on in any other than the correct position if the bent portion 9 isv held tightly against the side face ofthe `arm of the rule to which the body portionv is attached.

Also byproviding` the body portion with the integral spring` clip the rule cannot slip out of the pocket of the carrier. y y

It is to beunderstood that the attachment after once being placed on the rule is designed to remain there, and in no way is it designed to be removed unless the nails orscrews are forced out,` which Should only be done in case the attachment is destroyed l tened to a rule, comprising a body portion, the lower end being bent to form a clip, an

Copies ofv this patent may be obtained for arm formedr at the upper end of the body .portion extending' against oiie of the lon- 40 gitudinal edges'of the rule and then outwardly at right angles to the body portion.

3. In combination with a rule, an attachment fastened thereto, said attachment formed from a single blank of metal, the attachnient comprising a body portion fastened parallel with tlie member of the rule to which it is attached, the lower end of the bodyportioii being bent away from contact with the said member' and then toward the 50 said member again to form a springretain# nig` clip, an arm formed at the upper end of the body portion and formed to contact with one of the longitudinal edges of the said rule member and then at right angles to the rule member and body portion so as to permit the rule to be used as a square.

4. In combination with a rule, an attachment fastened thereto, said attachment formed from a single blank of metal, the at 60 Vta'chment comprising a body portion fastened parallel with the member of the rule to which it is fastened, the lower end of the body portion being bent awayV from contact with the said member and then toward the said member to form a springretaining clip, an arm formed at the upper end of the body portion and formed to Contact ujiziroiiew of the longitudinal edges of thewsaid rule member and then at right angles tothe rule 7( member and body portion so as to permit the rule to be used as a square, said body portion and said arm being graduated.

In testimony lwhereof I affix my signature.
